A True 1891 SS Target 1st Model?

[James K]

Looking at this 1891 Single Shot in .22 and trying to figure out if it's a true 1st Model or a 2nd or 3rd model modified revolver with a single shot barrel or even something else. Perhaps you can see that the blast shields were cut from the frame? I read they added the slots on the frame sides for balance.
It does have a 4-digit serial number on the front grip strap and does not appear on the butt. There is no visible number on the barrel. Can't see any pix of the top latch which should also have a matching serial number.
Here are some photos:

It is a 2nd Model, only one trigger pin, the 1st Models have 2 pins.

The Model 1891 Single Shot pistol had a recoil shield, yours does not. It also has a different top of barrel address including "MODEL OF 1891". The factory removed the recoil shields on all 2nd Model SS pistols.

The Model '91 frame was from their 3rd Model 38 revolver and some were made into combination kits like this one below. This is a reconstructed set similar to originals.

Thank you. Much value in the piece? I saw some plastic repro grips and screw kits for roughly $100.
I would certainly want to shoot it.
